Application of Diamond Dotted Paper in Transformers

Diamond Dotted Paper plays a vital role in transformers, and its application is mainly reflected in the following aspects:

1.Insulation

Diamond dotted paper is an electrical insulation material composed of paper-based material and adhesive coating, which has good insulation properties. In transformers, diamond dotted paper can effectively isolate different electrical parts to prevent current breakdown and short circuit. For example, when winding the transformer core, diamond dotted paper can be used as an insulating layer to ensure electrical isolation between the core and the winding. In addition, diamond dotted paper can also be used for terminal insulation to protect electrical connection points from interference from the external environment.

2.Improve mechanical strength

Diamond dotted paper not only has excellent insulation properties, but also has certain mechanical strength. In transformers, diamond dotted paper can withstand certain external force impact and vibration to ensure the stable operation of electrical equipment. This is of great significance to improving the reliability and durability of transformers.

3.Waterproof and moisture-proof

Diamond dotted paper also has the characteristics of waterproof and moisture-proof, which can effectively prevent moisture and moisture from eroding the internal electrical components of the transformer. In a humid environment, the waterproof and moisture-proof performance of the diamond dot glue paper is particularly important, which can ensure that the transformer can still work normally under harsh conditions.

4.Application Examples

Dry-type transformer: In a dry-type transformer, the application of diamond dot glue paper can isolate the winding and chip of the transformer to prevent leakage accidents caused by insulation damage.

Oil-immersed transformer: In an oil-immersed transformer, diamond dot glue paper can be used for insulation boards, insulation rings, and high-voltage insulation screens. For example, diamond dot glue paper is an insulating material commonly used in oil-immersed transformers, which has good insulation performance and mechanical strength.

5.Selection Recommendations

When choosing diamond dot glue paper for transformers, the following factors need to be considered:

Insulation performance: Ensure that the diamond dot glue paper has good insulation performance to meet the electrical isolation requirements of the transformer.

Mechanical strength: Select diamond dot glue paper with a certain mechanical strength to improve the reliability and durability of the transformer.

Waterproof and moisture-proof performance: For transformers used in humid environments, diamond dot glue paper with good waterproof and moisture-proof performance should be selected.

Price and cost: Under the premise of ensuring quality, consider the price and cost of diamond dot glue paper to ensure the economy of the transformer.

In summary, diamond dot glue paper has broad application prospects and important application value in transformers. By reasonably selecting and using diamond dot glue paper, the insulation performance, mechanical strength and waterproof and moisture-proof performance of the transformer can be effectively improved to ensure the safe and stable operation of the transformer.
